Corpse Explosion

[LGND24]

I am uncertain if this is a desired feature or a bug, but the Corpse Explosion skill does not deal damage scaled off of champion (or anything else with increased HP) monster's health. The damage dealt is equal to the base creature's stats, and not stats with the template additions. I suspect that the CE skill works as follows:

Cast->read monster type below/near cursor->find base health in registry (ignoring modifiers such as champion status or behemoth)->explode for damage equal to skill percentages.

Is it supposed to deal increased damage from tougher monster's corpses?
